| titleOfInvention | A kind of nitride near-infrared fluorescent material, preparation method and application thereof |
| abstract | The invention relates to a nitride near-infrared fluorescent material and a preparation method and application thereof. The general molecular formula of the nitride near-infrared fluorescent material is (Ca 1‑x‑y‑z Sr x Bay Eu z ) 3 [Li a Mg b Al c Si d ]N 6 , the Eu element enters the crystal lattice of at least one of Ca, Sr or Ba, as a light-emitting element and an activator; in the general molecular formula, 0≤x<1; 0≤ y≤0.3; 0<z≤0.02;3.4≤a≤4;0≤b≤0.2;0≤c≤0.4;1.8≤d≤2; a+2b+3c+4d=12. The material and its emission peak wavelength can reach up to 830nm through regulation, the half-peak width can reach up to 4283cm -1 , and the quantum yield can reach up to 77%. It has good application prospects in the fields of security and detection. Simultaneously, the preparation method is simple, and it is easy for industrialization to realize large-scale production. |
